Antibiotic Treatment for Pyogenic Flexor Tenosynovitis Following Animal Bites.

BACKGROUND: Pyogenic flexor tenosynovitis (PFT) is a common and severe hand infection. Patients who present early can be treated with intravenous antibiotics. OBJECTIVES: To determine whether PFT caused by animal bites and treated with antibiotics leads to a different outcome than other disease etiologies due to the extensive soft tissue insult and different bacterial flora. METHODS: We conducted a retrospective cohort study of 43 consecutive patients who presented with PFT between 2013 and 2020. The 10 patients who presented with PFT following an animal bite were compared to those who presented with PFT caused by any other etiology. RESULTS: Patients who were bitten pursued medical attention sooner: 1.9 ± 1.4 days compared with 5.3 ± 4.7 days (P = 0.001). Despite the quicker presentation, patients from the study group received similar antibiotic types and duration as controls. All patients were initially treated with intravenous antibiotics under surveillance of a hand surgeon. One patient (10%) from the study group and four controls (12%) were treated surgically (P = 1). Average follow-up was 17 ± 16 days. At the end of follow-up, one (10%) patient from the study group and three (9%) controls sustained mild range of motion limitation and one (3%) patient from the control group had moderate limitations (P = 0.855). CONCLUSIONS: Intravenous antibiotic treatment, combined with an intensive hand surgeon follow-up, is a viable option for the treatment of PFT caused by animal bites.

Proximal humeral nail for treatment of 3- and 4-part proximal humerus fractures in the elderly population: effective and safe in experienced hands.

BACKGROUND: Optimal treatment of 3- and 4-part proximal humerus fractures (PHFs) remains controversial. Although commonly recommended for less comminuted PHFs, the outcomes of treatment with proximal humerus nailing (PHN) are more equivocal. The purpose of this study was to report on radiographic and clinical outcomes of patients undergoing PHN fixation of 3- and 4-part PHFs at minimum one-year follow-up. Our hypothesis was that the findings would demonstrate satisfactory radiographic and clinical outcomes, with low rates of complications and revision surgeries. METHODS: Between 2008 and 2016, 121 patients with comminuted, low-energy, osteoporotic, PHFs underwent fixation via Targon PHN (Aesculap, Tuttlingen, Germany). Of these, 60 patients met inclusion and exclusion criteria and were included in this analysis (mean age 72; range 65-85). All completed a minimum 1-year follow-up (range 12.5-82 months). Patients with 3-part PHFs were compared to patients with 4-part PHFs. Clinical, radiographic, and functional outcomes were assessed at postoperative visits. Patient reported outcomes included pain, the American Shoulder and Elbow Surgeons (ASES) score and the Simple Shoulder Test (SST). Radiographic union and revision and complication rates were assessed. RESULTS: Overall, 37 (62%) fractures were classified as Neer 3 and 23 (38%) were classified as Neer 4. Both groups achieved similar postoperative range of motion. Patients with 3-part fractures reported significantly lower postoperative pain (0.76 ± 1.8 vs. 1.65 ± 2.2, p = 0.0047). Patients with 3-part fractures reported significantly better ASES scores (82.4 ± 19.2 vs. 70.8 ± 21.9, p = 0.02) and non-statistically significant higher SST scores (8.4 ± 3.2 vs. 7.43 ± 3.8, p = 0.14). Adequate fracture union was achieved in 53 fractures (88.3%). Three patients (5%) had varus malunion or greater tuberosity displacement, one (1.7%) had mechanical failure, and three (5%) had radiographic evidence of avascular necrosis. Between groups, there was no difference in failure rates. CONCLUSION: Proximal humeral nails can successfully be used by experienced surgeons in fixation of comminuted and displaced proximal humeral fractures in selected patients with osteoporosis. While patients with both 3- and 4-part fractures demonstrate fracture union with satisfactory outcomes, patients with 3-part fractures demonstrate significantly higher postoperative functional scores.

The medial border of the tibial tuberosity as an auxiliary tool for tibial component rotational alignment during total knee arthroplasty (TKA).

PURPOSE: The objective of this study was to quantify the amount of ensuing internal rotation of the tibial component when positioned along the medial border of the tibial tubercle, thus establishing a reproducible intraoperative reference for tibial component rotational alignment during total knee arthroplasty (TKA). METHODS: The angle formed from the tibial geometric centre to the intersection of both lines from the middle of the tibial tuberosity and its medial border was measured in 50 patients. The geometric centre was determined on an axial CT slice at 10 mm below the lateral tibial plateau and transposed to a slice at the level of the most prominent part of the tibial tuberosity. Similar measurements were taken in 25 patients after TKA, in order to simulate the intraoperative appearance of the tibia after making its proximal resection. RESULTS: This angle was found to be similar (n.s.) in normal and post-TKA tibiae [median 20.4° (range 15°-24°) vs. 20.7° (range 16°-25°), respectively]. In 89.3 % of the patients, the angle ranged from 17° to 24°. No statistical difference (p n.s.) was found between women and men in both normal [median -20.7° (range 16°-25°) vs. 19.9° (range 15°-24°)] and post-TKA tibiae [median 21.4° (range 19°-24°) vs. 20° (range 16°-25°)]. CONCLUSION: This study found that in 90 % of the patients, the medial border of the tibial tuberosity is internally rotated 17°-24° in relation to the line connecting the middle of the tuberosity to the tibial geometric centre. Since this anatomical landmark may be more easily identifiable intraoperatively than the commonly used "medial 1/3", it can provide a better quantitative reference point and help surgeons achieve a more accurate tibial implant rotational position. LEVEL OF EVIDENCE: Cohort and case control studies, Level III.

[BISPHOSPHONATES AS A PREVENTATIVE TREATMENT FOR OSTEOPOROTIC HIP FRACTURES: A MIXED BLESSING].

BACKGROUND: The widespread use of bisphosphonates for treating osteoporosis in the last two decades has raised concern about the complication of atypical hip fractures secondary to bisphosphonate treatment. These fractures may be the result of a minor trauma to the hip or without any trauma at all. It may be heralded by prodromal groin or hip pain. Prolonged bisphosphonate treatment and atypical fractures may exist, but the nature and the extent of this linkage are still unknown. Currently, there is a lack of adequate evidence-based methods or a consensus about the treatment of this unique phenomenon. METHODS: We retrospectively examined the records of all subtrochanteric hip fracture cases admitted to our department in the years 2010-2014. During that period, we treated a total of 1315 patients:726 patients with pertrochanteric fractures, 514 patients with subcapital fractures and 75 patients with distal subtrochanteric fractures. Among those, 16 patients (1.2%) qualified as atypical hip fractures. The location of the fracture, period of bisphosphonates use, fixation type, complications and recovery were recorded. RESULTS: The average age of the patients in our study was 76.9 years. All patients were treated with bisphosphonates and over 80% of the patients were treated specifically with Alendronate prior to the fracture. Mean treatment time was 7.8 years. Most of the fractures (75%) were subtrochanteric, and the others were at the femur midshaft. All patients received surgical fixation and all accomplished union of the fractures. CONCLUSIONS: It seems reasonable to assume a causative relationship between a long term use of bisphosphonates and the occurrence of atypical hip fractures. It is a relatively rare complication; nevertheless, it should be kept in mind during a long term use of bisphosphonates. According to our department's clinical experience we found no delay in bone union with these atypical hip fractures. It seems reasonable to prophylactically fixate atypical stress fractures before they become a full fracture.

Which patients are less likely to improve during the first year after arthroscopic partial meniscectomy? A multivariate analysis of 201 patients with prospective follow-up.

PURPOSE: To determine which specific factors influence the improvements in function and pain at the first year following arthroscopic partial meniscectomy. METHODS: Between 2012 and 2013, patients who had arthroscopic partial meniscectomy were included (n = 201) and followed prospectively before surgery and at 12 months. Multivariable stepwise analysis included preoperative variables (age, gender, limb side, height, weight, body mass index, comorbidities, smoking, Tegner activity scale, Lysholm knee score, preceding injury and duration of preoperative symptoms) and arthroscopic findings (degree of cartilage lesions, medial or lateral meniscus involvement, type of meniscal tear and concomitant cruciate tear). The Lysholm clinical score at the last follow-up and the time interval for substantial pain relief was modelled as a function of the above predictor variables. RESULTS: At the last follow-up, the mean Lysholm score improved by 14.6 points (95 % CI 10.4-18.8, P < 0.001), from 68.0 ± 16.1 to 82.6 ± 19.6 points and 153 (76 %) patients declared they were satisfied to have had the operation. The mean time interval for substantial pain relief was 3.5 ± 1.5 months. Females and patients with lower preoperative Lysholm score were correlated with lower post-operative Lysholm score, while females and patients with lateral meniscal tears (compared to medial meniscal tears) were correlated with longer recovery. CONCLUSIONS: Arthroscopic partial meniscectomy improved pain and function at the first year post-operatively. Female gender, lateral meniscal tear and less favourable preoperative function were relatively correlated to worse post-operative function and longer rehabilitation time. LEVEL OF EVIDENCE: IV.

The Sphygmomanometer Pain Test: A Simple Method for Identifying Patients at Risk of Excessive Pain after Total knee Arthroplasty.

BACKGROUND: Despite the overall success of total knee arthroplasty (TKA), a relatively large proportion of patients remain dissatisfied with the outcome. We hypothesized that patients with a lower threshold for pain were more likely to have worse outcomes after TKA. METHODS: Forty-eight consecutive patients with primary knee osteoarthritis graded a standardized painful stimulus caused by inflating a sphygmomanometer placed on the forearm, on a visual analog scale (VAS) scale before their TKA. We compared the VAS scores to patients' Knee Society scores and Knee Society function scores 2 years after TKA. RESULTS: Patients with a severe VAS score (>74 mm) had significantly worse Knee Society scores compared to patients with mild (0-44 mm) and moderate (45-74 mm) VAS scores (55 ± 20.5 vs 81.5 ± 11.1 and 84.8 ± 13, respectively, P = .04) and worse Knee Society Function scores (34 ± 20.7 vs 75.2 ± 17.3 and 77 ± 17.4, respectively, P = .027) at 2 years after TKA. CONCLUSIONS: Patients with a lower threshold for pain, as determined by a standardized painful stimulus, are more likely to have lower Knee Society pain and function scores after TKA.

The Use of a Supra-Acetabular Antibiotic-Loaded Cement Shelf to Improve Hip Stability in First-Stage Infected Total Hip Arthroplasty.

BACKGROUND: Antibiotic-loaded cement spacers in first-stage revision total hip arthroplasty (THA) for managing infection are associated with high dislocation and fracture rates. The aim of this study was to report the use of an antibiotic-loaded cemented supra-acetabular roof augmentation to reinforce hip stability after cement spacer insertion for first-stage total hip revision in the treatment of infected THA. METHODS: We retrospectively reviewed a consecutive series of 50 THAs involving 47 patients with an infected hip requiring staged revisions of THA. We documented dislocation, reinfection, and time for revision and outcome. RESULTS: There were no cases of hip dislocation, cement fractures, or any other technical complications associated with the use of the roof augmentation lip. Thirteen cases (26%) had a cemented spacer for longer than 120 days. Seven (14%) cases had recurrent infection after staged revision THA. CONCLUSION: The antibiotic-loaded cemented supra-acetabular roof augment improved femoral head spacer coverage for patients requiring a staged revision THA for infection.

Arthroscopic meniscectomy of traumatic versus atraumatic tears in middle aged patients: is there a difference?

INTRODUCTION: Meniscal tears can be classified in various ways, one of which is into traumatic or degenerative. It is not known whether partial meniscectomy of clinically defined traumatic compared to degenerative tears in middle age patients has favorable results. The purpose of this study was to compare the outcome after arthroscopic partial meniscectomy of clinically defined traumatic to degenerative meniscal tears in middle age patients. MATERIALS AND METHODS: Eighty-six middle aged patients with stable knees and no radiographic signs of osteoarthritis who had arthroscopic partial meniscectomy were divided into a study group of 43 patients with a preceding knee injury related to their knee symptoms (traumatic group) and a control group of 43 uninjured patients (atraumatic group), matched by age, sex, body mass index and comorbidities. The surgical findings and postoperative clinical scores were compared between the two groups. RESULTS: There were no statistical differences in surgical findings of tear types and degree of chondral lesions. At the end of the follow-up 33 (77 %) patients in each group were satisfied to have had the operation. The median Lysholm score improved from 65.9 ± 17.4 to 77.4 ± 21.2 points (P = 0.001) in the traumatic group and from 65.3 ± 17 to 82.4 ± 17.7 in the atraumatic group (P < 0.0001). CONCLUSIONS: Arthroscopic partial meniscectomy in middle aged patients with stable knees and no signs of radiographic osteoarthritis improve pain and function. There were no differences in surgical findings and short term clinical outcome between patients with and without preceding knee injury.

Distal femoral varus osteotomy combined with tibial plateau fresh osteochondral allograft for post-traumatic osteoarthritis of the knee.

PURPOSE: This study was conducted to examine the long-term survivorship and functional outcome of distal femoral varus osteotomy with fresh osteochondral allograft following failed lateral tibial plateau fracture surgery. We hypothesized that this procedure would be associated with a low rate of conversion to total knee arthroplasty (TKA) at medium to long-term follow-up. METHODS: A consecutive series of 27 of distal femoral varus osteotomy combined with fresh osteochondral allograft following (27 patients) conducted between January 1981 and January 2005 for failed lateral tibial plateau fracture was retrospectively reviewed. Outcome measures included the Knee Society Knee Score (KSKS) and Knee Society Function Score (KSFS) and conversion rates to TKA. RESULTS: The study group consisted of 15 females (55.6 %) and 12 males (44.4 %), with a median age of 41.2 years (range 17-62 years). The median follow-up was 13.3 years (range 2-31 years). The knee function scores improved significantly at 2 years post-surgery (p < 0.01) from a median of 54.6 points preoperatively to 83.8 points (KSKS) and median of 50.6 points to 71.1 points (KSFS) at 2 years post-distal femoral varus osteotomy with fresh osteochondral allograft following surgery. At most recent follow-up, 4/27 patients had required conversion to TKA, and one patient had fractured the FOCA, requiring revision of the allograft. The survivorship for distal femoral varus osteotomy with fresh osteochondral allograft following was 88.9 ± 4.6 % at 10 years, 71.4 ± 18.1 % at 15 years, and 23.8 ± 11.1 % at 20 years. CONCLUSION: The use of distal femoral varus osteotomy combined with fresh osteochondral allograft following in patients with failed lateral tibial plateau fracture results in the majority of patients having good or excellent clinical outcomes and significantly delays the need for TKA in most patients. LEVEL OF EVIDENCE: Case series, Level IV.

Gender differences in the accuracy of joint line tenderness for arthroscopically confirmed meniscal tears.

INTRODUCTION: The reliability of joint line tenderness was previously investigated among other clinical tests for the diagnosis of meniscal pathology with variable results. The aim of this study was to evaluate and compare the accuracy of joint line tenderness as a clinical diagnosing test for arthroscopically confirmed meniscal tears between males and females. MATERIALS AND METHODS: For the purpose of preoperative joint line tenderness accuracy calculations, this study included male and female groups of patients who have had knee arthroscopy following preoperative diagnosis of meniscal tear. Overall, 195 patients were included in the study, 134 males and 61 females. The mean age was 43.4 (13-76) years. RESULTS: In the male group, the diagnosis of meniscal tear by joint line tenderness was correct in 84 (62.7%) of 134 knees for the medial side and in 115 (85.8%) for the lateral side. In the female group, the diagnosis was correct in 35 (57.4%) of 61 knees for the medial side and in 57 (93.4%) for the lateral side. In order to refine the accuracy of medial joint line tenderness, the data were recalculated for patients with medial meniscal tears and no chondral lesion or cruciate ligament tears; however, the accuracy remained low. CONCLUSIONS: The physical finding of joint line tenderness of the knee as a test for lateral meniscal tear was found reliable in both males and females. For medial meniscal tears, the test had low reliability and thus less useful if used alone, in both genders.

Acetabular cup revision combined with tensor facia lata reconstruction for management of massive abductor avulsion after failed total hip arthroplasty.

We report on 17 patients with massive abductor avulsions after total hip arthroplasty (THA) treated with medialization of the acetabular component and tensor fascia lata (TFL) reconstruction. All patients had severe limp, positive Trendelenburg sign, and avulsion of the abductor insertion confirmed on MRI. Mean age was 69 years (range, 50-83 years), and mean follow-up period was 36 months (range, 18-78 months). After surgery, 9 patients had no limp (47%), 8 patients had a mild limp, and abductor power improved from mean 2.5/5 to mean 3.8 (P < 0.0001). At latest follow-up, the Harris Hip Score was excellent in 6 hips (37%), good in 7 (43%) hips, and fair or poor in 3 (23%). Two patients with mild limp were not satisfied with their procedure.

Dislocation after the first and multiple revision total hip arthroplasty: comparison between acetabulum-only, femur-only and both component revision hip arthroplasty.

BACKGROUND: Dislocation may complicate revision total hip arthroplasty (THA). We examined the correlation between the components revised during hip arthroplasty (femur only, acetabulum only and both components) to the rates of dislocation in the first and multiple revision THA. METHODS: We obtained data from consecutive revision THAs performed between January 1982 and December 2005. Patients were grouped into femur-only revision, acetabulum-only revision and revision THA for both components. RESULTS: A total of 749 revision THAs performed during the study period met our inclusion criteria: 369 first-time revisions and 380 repeated revisions. Dislocation rates in patients undergoing first-time revisions (5.69%) were significantly lower than in those undergoing repeated revisions (10.47%; p = 0.022). Within the group of first-time revisions, dislocation rates for acetabulum-only revisions (10.28%) were significantly higher than those for both components (4.61%) and femur-only (0%) reconstructions (p = 0.025). CONCLUSION: Although patients undergoing first-time revisions had lower rates of dislocations than those undergoing repeated revisions, acetabulum-only reconstructions performed at first-time revision arthroplasty entailed an increased risk for instability.

CONTEXTE: Il arrive que la dislocation vienne compliquer la révision des prothèses totales de la hanche (PTH). Nous avons analysé la corrélation entre les éléments révisés durant une arthroplastie de la hanche (fémur seulement, acétabulum seulement ou les 2 éléments) et le taux de dislocation qui accompagne une première ou de multiples révisions de PTH. MÉTHODES: Nous avons obtenu les données sur les révisions de PTH consécutives effectuées entre janvier 1982 et décembre 2005. Les patients ont été regroupés selon que la révision de leur PTH concernait le fémur seulement, l'acétabulum seulement ou les 2 éléments. RÉSULTATS: En tout, 749 révisions de PTH effectuées au cours de la période de l'étude répondaient à nos critères d'inclusion : 369 premières révisions et 380 révisions additionnelles. Les taux de dislocation ont été significativement moins élevés chez les patients soumis à une première révision (5,69 %) que chez les patients qui n'en étaient pas à leur première révision (10,47 %; p = 0,022). Dans le groupe soumis à une première révision, les taux de dislocation consécutive à une révision concernant uniquement l'acétabulum (10,28 %) ont été significativement plus élevés que dans les groupes qui ont subi des reconstructions des 2 éléments (4,61 %) ou du fémur seulement (0 %, p = 0,025). CONCLUSION: Même si les patients soumis à une première révision ont présenté des taux moindres de dislocation que ceux qui n'en étaient pas à leur première révision, les premières révisions d'arthroplastie impliquant une reconstruction de l'acétabulum seulement ont comporté un risque plus grand d'instabilité.

Atypical fractures of the femur related to prolonged treatment with bisphosphonates for osteoporosis.

BACKGROUND: Bisphosphonates reduce the overall risk of fractures among patients with osteoporosis, and this beneficial effect is long-lasting. However, since bisphosphonates inhibit bone remodeling, they may enhance the formation and propagation of micro-cracks over time and patients may therefore be prone to atypical fatigue fractures, mainly in the subtrochanteric region and femoral shaft. OBJECTIVES: To present two cases of subtrochanteric fractures related to bisphosphonate treatment, and review the current literature. CONCLUSIONS: Despite the overall beneficial effect of bisphosphonates, further research is required to prevent this significant complication.

Intramedullary nailing without curettage and cement augmentation for the treatment of impending and complete pathological fractures of the proximal or midshaft femur.

Metastases in the proximal femur and in the femoral diaphysis are usually treated with either cephalomedullary or intramedullary nailing. The benefit of curettage and augmentation of the nail with methyl methacrylate remains controversial. The authors retrospectively studied the outcomes with cephalomedullary and intramedullary nailing without curettage and methyl-methacrylate augmentation for lytic metastases of the proximal/diaphyseal femur. Twenty-one complete (11) or impending (10) pathological fractures in 19 consecutive patients were treated between January 2006 and August 2013. There were 11 women and 8 men. Their mean age was 62 years (range, 38 to 87). All patients received adjuvant chemotherapy or radiotherapy.The average postsurgical survival was 9.7 months (range 1-36 months). A single deep infection was debrided. Seventeen out of 19 patients were ambulatory, with or without a walking aid. No implant failure was noted. In other words, patients succumbed to the disease prior to hardware failure. Femoral nail insertion without curettage and cement augmentation provided satisfactory stabilization of proximal and diaphyseal femur fractures, impending or complete, even when there was massive bone destruction.

Acetabular alignment and primary arc of motion for minus, skirtless, and skirted 28-, 32-, 36-, and 40-mm femoral heads.

We examined the influence of acetabular cup alignment on the primary arc of motion (PAOM) for minus (-3.5), skirtless (+3.5), and skirted (+10.5) neck lengths with 28-, 32-, 36-, and 40-mm femoral heads. Total hip arthroplasty was performed in a pelvic saw bone model. The acetabulum was positioned in 30°/45°/60° abduction and 0°/15°/30° anteversion, respectively. The PAOM was determined using a digital inclinometer for each of the acetabular positions and 12 femoral heads mentioned above. Best PAOM was found in 45° abduction and 15° to 30° anteversion as well as 60° abduction and 0° anteversion. Combinations of excessive abduction and anteversion as well as horizontalization and retroversion resulted in the worst PAOM. Primary arc of motion is mainly determined by cup alignment even when using larger femoral heads.

Total hip arthroplasty in Down syndrome patients: an improvement in quality of life: replacement arthroplasty in Down syndrome (RADS) study group.

The purpose this study was to assess survival rates, clinical outcomes, and radiographic outcomes of total hip arthroplasty in Down syndrome patients. We reviewed 26 total hip arthroplasties (21 patients) performed by four experienced hip surgeons. These patients had a mean age of 35 years and a mean follow-up of 106months. Clinical outcomes were assessed using Harris Hip scores, and radiographic evaluation for component fixation and migration was performed. The overall survival with aseptic failure as an endpoint was 85%. The mean Harris Hip score improved to 84 points at final follow-up. While these patients can be challenging to treat, excellent surgical technique and selective use of acetabular constraint can reliably provide patients with excellent pain-relief and improved function.

Reversed assembly of total hip arthroplasty components: a surgical tip to facilitate implant reduction during minimally invasive surgery.

Total hip arthroplasty (THA) using minimally invasive surgery (MIS) can result in soft tissue damage during the trial reduction and actual implantation. We present a surgical technique that reduces soft tissue trauma and facilitates implant reduction while protecting the prosthetic head from scratching during MIS THA. Primary THA using MIS was performed in 16 hips through a transgluteul direct lateral approach. Average follow-up was 54 months (range 52-58 months). At latest follow-up there was no evidence for component dissociation or loosening in any of the patients. Reverse assembly of THA components is a viable option, which may facilitate MIS THA and decrease soft tissue trauma.

Fresh-stored osteochondral allografts for the treatment of femoral head defects: surgical technique and preliminary results.

PURPOSE: The purpose of this study was to present the preliminary clinical and radiographic outcomes of the treatment of femoral head osteochondral defects in eight consecutive symptomatic patients with fresh-stored osteochondral allografts via a trochanteric osteotomy. METHODS: This study included all consecutive patients treated in our department between 2008 and 2010 for worsening pain and mechanical symptoms of femoral head osteochondral defects. Each patient had preoperative routine hip radiographs and a preoperative magnetic resonance imaging study that determined and recorded the defect size and femoral head diameters. Allograft donors were identified through the Multiple Organ Retrieval and Exchange program (Ontario, Canada). RESULTS: The osteochondral defects were secondary to osteochondritis dissecans in four patients, avascular necrosis in three and femoral head fracture without dislocation in one. The patients' average age at surgery was 23.7 (range 17-42), and the average follow-up was 41 months (range 24-54). Follow-up included clinical and radiographic examinations at standard intervals. The average Harris hip scores improved from 57.7 (range 50-65) points preoperatively to 83.9 (range 72-94) points at latest follow-up. Five patients had good-to-excellent clinical outcomes, and one had a fair outcome. One patient was converted to a total hip arthroplasty due to progression of arthritis. Another patient's graft subsided and he underwent a successful repeat transplantation. An additional patient required the removal of the screws transfixing her trochanter due to persistent irritation. CONCLUSIONS: These findings indicate that fresh-stored osteochondral allograft transplantation using a trochanteric slide and surgical dislocation is a viable treatment option for femoral head defects in young patients.
