osteotomy\n\nA shortening osteotomy is a reconstructive operation that cuts a long bone and removes a segment so the limb becomes shorter, most often to equalize leg lengths, reduce tension on nerves or soft tissue, or correct deformity.[1](https://www.hss.edu/globalassets/files/tibial-femoral-osteotomy-chapter-45.pdf) It sits alongside other limb-length management options: epiphysiodesis of the longer limb in a growing child, and gradual lengthening of the shorter limb.[2](https://journals.lww.com/jpo-b/fulltext/2024/11000/are_percutaneous_epiphysiodesis_and_phemister.5.aspx) • [3](https://www.researchgate.net/publication/21567620_Bilateral_femoral_shortening_for_unaccepted_tallness) Femoral shortening for leg-length discrepancy is performed infrequently, because most discrepancies are recognized before skeletal maturity, the point at which correction is ideally timed.[4](https://www.mayoclinicproceedings.org/article/S0025-6196%2825%2900640-8/fulltext)\n\n| Key fact | Detail |\n|---|---|\n| Typical femoral resection | 1.5 to 4.5 cm in a nail-fixed subtrochanteric series (mean 3.3 cm)[5](https://pubmed.ncbi.nlm.nih.gov/23306289/); up to 7.5 cm reported without loss of function[6](https://orthoarchives.com/en/orthoscience/article/W2134766182) |\n| Safe tibial shortening | Up to 5 cm reported in men of normal height[6](https://orthoarchives.com/en/orthoscience/article/W2134766182) |\n| Sciatic nerve threshold | Lengthening of more than 4 cm in THA for high hip dysplasia is associated with sciatic nerve injury, motivating shortening[7](https://boneandjoint.org.uk/Article/10.1302/1358-992X.2024.16.019) |\n| Femoral union time | 3 to 4 months in step-cut series (average 3.6 months)[8](https://pubmed.ncbi.nlm.nih.gov/6641045/); mean 4.8 months in nail-fixed series[5](https://pubmed.ncbi.nlm.nih.gov/23306289/) |\n| Weil metatarsal shortening | Average 4.0 mm (second) and 3.8 mm (third) metatarsal[9](https://www.acfas.org/getattachment/e4417100-9d91-4ec8-9a8d-fd7b598e0582/POST2020_SCI-511.pdf?lang=en-US) |\n| Weil nonunion rate | 0 to 2%, with immediate weightbearing allowed[10](https://www.revesppod.com/Documentos/ArticulosNew/S0210123817300658.pdf) |\n| Pooled nerve palsy rate (subtrochanteric osteotomy in THA) | 2.63% (95% CI 1.60% to 3.87%)[11](https://bmcmusculoskeletdisord.biomedcentral.com/counter/pdf/10.1186/1471-2474-15-331.pdf) |\n\n## How it works\n\nShortening removes bone from the longer or deformed limb rather than adding length to the other. In adults with leg-length inequality, subtrochanteric femoral shortening osteotomy fixed with an interlocking intramedullary nail is described as a good alternative in patients in whom the Ilizarov method is contraindicated.[5](https://pubmed.ncbi.nlm.nih.gov/23306289/) In hip reconstruction for high developmental dysplasia, the rationale is neurovascular: lengthening the limb by more than 4 cm to bring the dislocated femoral head down to the acetabulum is associated with sciatic nerve injury, so the femur is shortened instead.[7](https://boneandjoint.org.uk/Article/10.1302/1358-992X.2024.16.019)\n\nThe contrast with gradual correction is one of biology and logistics. Bone regenerates across a low-energy osteotomy when stability is adequate and distraction proceeds at about 1 mm per day divided into 3 to 4 daily adjustments; gradual correction is indicated for large deformity, a compromised soft-tissue envelope, or the need for [bone lengthening](https://www.edgepedia.org/bone-lengthening).[1](https://www.hss.edu/globalassets/files/tibial-femoral-osteotomy-chapter-45.pdf)\n\n## How it is done\n\n**Femoral shortening** is most commonly performed in the subtrochanteric region. In one series of 14 adults with discrepancies of 1.5 to 6.0 cm, the planned segment was resected through a subtrochanteric osteotomy and fixed with an interlocking intramedullary nail, achieving the expected shortening in all patients.[5](https://pubmed.ncbi.nlm.nih.gov/23306289/) An earlier step-cut series used Küntscher rod fixation in 14 adults with discrepancies averaging 5.6 cm, resecting an average of 5.0 cm (range 2.7 to 7.5 cm).[8](https://pubmed.ncbi.nlm.nih.gov/6641045/) Less invasive options exist: the bone can be sectioned percutaneously over a nail using a multiple drill-hole technique with an intramedullary saw and chisel, the osteotomized bone being smashed and left in place. [Plate fixation](https://www.edgepedia.org/plate-fixation) is an alternative; a proximal femoral locking plate (such as the Synthes LCP Proximal Femoral Plate 4.5/5.0) applied with locking and non-locking screws under image intensifier control can stabilize the osteotomy, and gaps may be left ungrafted.[12](https://pmc.ncbi.nlm.nih.gov/articles/PMC8921383/) With Ilizarov-type ring fixation, 1 to 2 pins are placed above the lesser trochanter and 3 to 4 in the femoral shaft, with one ring or ring block on each segment.[13](https://www.hss.edu/globalassets/files/LL/LL-Femoral-osteotomy.pdf) A four-patient series used patient-specific osteotomy guides with robot-assisted fixation for femoral shortening with varus deformity, reporting no deep infection, nonunion, or unplanned reoperation.[14](https://link.springer.com/article/10.1186/s13018-026-07186-4)\n\n**Metatarsal shortening (Weil osteotomy)** is an intra-articular, joint-preserving cut through the distal metatarsal, made parallel to the weight-bearing surface, that shifts the plantar fragment proximally to shorten an excessively long metatarsal and restore the metatarsal parabola.[10](https://www.revesppod.com/Documentos/ArticulosNew/S0210123817300658.pdf) Because the cut is inherently stable, several fixation options work: two parallel or crossed Kirschner wires, a threaded wire, a 2.0 mm non-lagged minifragment screw, a 2.4 mm Herbert-type cannulated screw, or dedicated snap-off screws; one textbook protocol specifies a 2-mm titanium snap-off screw, 12 mm long for the second metatarsal and 11 mm for the others, with weightbearing in a postoperative shoe from the first postoperative day.[15](https://doctorlib.org/surgery/operative-techniques-orthopaedic-surgery/439.html)\n\n## Origin\n\nOperative shortening of the lower limb was addressed in early orthopedic literature, including a paper from the Orthopaedic Clinic of the Karolinska Institute in Stockholm that framed equalizing the lengths of the right and left legs as a problem with several theoretical options.[16](https://actaorthop.org/actao/article/download/31061/35951/84607)\n\n## Variants\n\nSubtrochanteric cut shapes are grouped into four types: transverse, oblique, chevron, and step-cut.[17](https://www.intechopen.com/chapters/1198345) Reviews also list Z-shaped and double-chevron configurations.[18](https://pmc.ncbi.nlm.nih.gov/articles/PMC8891993/) Modified cuts (step-cut, oblique, chevron) were introduced to improve rotational stability, since the centrosymmetric transverse cut surface offers little resistance to rotation; transverse cuts are nonetheless the easiest to perform and the most widely used.[11](https://bmcmusculoskeletdisord.biomedcentral.com/counter/pdf/10.1186/1471-2474-15-331.pdf) A systematic review of 53 studies (1,925 hips) found the transverse subtrochanteric technique most frequent, with nonunion ranging from 0% (step-cut) to 2% (transverse), rising to 4% (95% CI 0 to 9%) with cemented stems; stem aseptic loosening ranged from 7.14% (Z osteotomy) to 0% (step-cut and V-shaped), and oblique osteotomy had the highest infection rate at 2.63%.[19](https://orthoarchives.com/en/orthoscience/article/W7127562796) A meta-analysis of 37 studies (795 hips) found no significant difference between transverse and modified osteotomies in nonunion, nerve palsy, dislocation, revision, or [Harris hip score](https://www.edgepedia.org/harris-hip-score) improvement.[11](https://bmcmusculoskeletdisord.biomedcentral.com/counter/pdf/10.1186/1471-2474-15-331.pdf) One clinical series judged transverse osteotomies the most technically efficient, versatile, and predictable because they allow rotation correction while preserving metaphyseal bone.[7](https://boneandjoint.org.uk/Article/10.1302/1358-992X.2024.16.019)\n\nAt the metatarsal level, the triple Weil (three-cut) osteotomy is used for propulsive metatarsalgia; in 29 non-fixed triple-cut feet, features of nonunion appeared in 2 feet (4%), both asymptomatic, while 5 of 15 fixed feet lost fixation.[20](https://www.ejcrim.com/index.php/mltj/article/download/6791/5471)\n\n## Applications\n\nShortening osteotomy is used in leg-length inequality in skeletally mature patients, where femoral shortening is considered safer than tibial shortening.[3](https://www.researchgate.net/publication/21567620_Bilateral_femoral_shortening_for_unaccepted_tallness) In total hip arthroplasty for high developmental dysplasia, the femur must be shortened to seat the prosthesis without overstretching the sciatic nerve.[7](https://boneandjoint.org.uk/Article/10.1302/1358-992X.2024.16.019) In forefoot surgery, the Weil osteotomy treats metatarsalgia from an excessively long metatarsal and from subluxated or dislocated metatarsophalangeal joints, and its triple variant addresses propulsive metatarsalgia.[10](https://www.revesppod.com/Documentos/ArticulosNew/S0210123817300658.pdf) A related strategy, acute shortening and relengthening (ASRL), manages metaphyseal bone defects of 2 to 10 cm in lower limb long bones as an alternative to bone transport: the limb is shortened acutely to close the defect, then re-lengthened.[21](https://boneandjoint.org.uk/Article/10.1302/0301-620X.107B12.BJJ-2024-0882.R2)\n\n## Limitations and alternatives\n\nUnion is the main femoral concern. In the nail-fixed subtrochanteric series, union occurred in 8 of 14 patients at 3.5 to 6 months (mean 4.8 months); 3 had delayed union at 10 to 12 months, and 3 nonunions required further surgery.[5](https://pubmed.ncbi.nlm.nih.gov/23306289/) Closed femoral shortening has been associated with malrotation, loss of function, and acute respiratory distress syndrome after reaming, so a nail locked proximally and distally with cautious reaming is recommended.[3](https://www.researchgate.net/publication/21567620_Bilateral_femoral_shortening_for_unaccepted_tallness) In dysplasia series, malrotation of 3 and 5 degrees occurred in two patients and three had transient sciatic nerve palsies.[7](https://boneandjoint.org.uk/Article/10.1302/1358-992X.2024.16.019) The most reliable femoral method in one 46-operation review was open subtrochanteric osteotomy preserving the isthmus with a proximally locked nail; most complications arose from inadequate stabilization.[6](https://orthoarchives.com/en/orthoscience/article/W2134766182) Weil-specific failures include the floating toe, reported as the most important complication,[22](https://www.cureus.com/articles/84695-biomechanical-analysis-of-the-change-of-the-metatarsophalangeal-joints-center-of-rotation-after-weil-and-triple-weil-osteotomies-a-comparative-cadaveric-study) plus stiffness, dorsiflexed contracture, and transfer metatarsalgia with excessive shortening.[15](https://doctorlib.org/surgery/operative-techniques-orthopaedic-surgery/439.html)\n\nAlternatives depend on age and discrepancy size. Epiphysiodesis of the longer limb suits predicted discrepancies of 2 to 5 cm at maturity but requires open physes and remaining growth, and comes in permanent and temporary forms.[2](https://journals.lww.com/jpo-b/fulltext/2024/11000/are_percutaneous_epiphysiodesis_and_phemister.5.aspx) For discrepancies greater than 10 cm, lengthening is preferred, although a one-stage two-limb procedure can shorten the longer limb and implant the excised bone in the contralateral limb being lengthened.[3](https://www.researchgate.net/publication/21567620_Bilateral_femoral_shortening_for_unaccepted_tallness) How shortening osteotomy compares with a simple shoe lift, and its role in [Freiberg disease](https://www.edgepedia.org/freiberg-disease) or [hallux valgus surgery](https://www.edgepedia.org/hallux-valgus-surgery), is not addressed by the published comparisons covered here.\n\n## References\n\n1.
