[Comparison between different anchors for zone I flexor tendon repair]. / Comparaison des différentes ancres dans les réinsertions transosseuses de tendons fléchisseurs profonds en zone I.

INTRODUCTION: Transosseous reinsertion has been used to complement the Bunnell pull-out technique in the repair of zone I deep flexor tendon injuries. The aim of this study is to compare the different devices on the market in terms of complication, functional recovery and ease of use. MATERIAL AND METHOD: This is a single-center study including all patients who underwent transosseous anchor reinsertion from 2010 to 2021 with a minimum of 6 months of follow-up. Twenty-seven patients were included. The anchors used were of different types: Microfix® Quickanchor plus® and Miniquick anchor® from DePuy Mitek; Juggerknot® Soft Anchor 1.0mm from Zimmer-Biomet; or Kerifix® 4.0 from KeriMedical. We analyzed intraoperative data, complications and functional recovery by quickDASH score. RESULTS: The average age was 38.6 years (± 16.1), the demographic characteristics were identical in the different groups. There was a significant difference in the number of anchors used intraoperatively before definitive placement (P=0.02), to the disadvantage of the Juggerknot® anchors. There was no significant difference in terms of complications and functional recovery evaluated by the quickDASH. CONCLUSION: Our study did not find significant differences between the different anchors in terms of complications and functional recovery. Some anchors seem to have a better grip during placement than others.

[Emergency free flap in reconstruction of the lower limb: About 23 cases over 11 years]. / Reconstruction des pertes de substance des membres inférieurs par lambeau libre en urgence : à propos de 23 cas sur 11 ans.

OBJECTIVES: To study the coverage period influence and various parameters concerning the microsurgical act on the patient clinical outcomes. METHODS: We report 23 cases of reconstruction of lower limb loss of substance by free flap operated from 2010 to 2021. Among them, 9 patients were operated on as an emergency versus 14 in the secondary or late phase of the trauma. RESULTS: The average age of injured patients operated on emergency was 42 years (17-68 years) and 34 years for the patients who undergo deferred surgery (17-57 years). The sex ratio (female/male) was 22% in patients operated on urgently and 7% in patients operated on later. Regarding the type of free flap, it was Serratus anterior muscle flap in 10 cases, Latissismus dorsi flap in 9 cases, ALT flap in 3 cases and Gracilis muscle flap in 1 case. There were 2 failures of vascularized free transfer (8.7%) with complete necrosis of the flap and 3 revision surgeries on venous thrombosis which finally made it possible to obtain 3 flap successes. We analyze the results (complications/osteitis) according to the time to coverage. CONCLUSIONS: In our study, we did not find any significant difference between the groups operated in emergency and at a distance concerning the rate of infection and failure of the flaps.

[The evolution of phosphocalcic cement in phalangeal and metacarpal enchondromas. A retrospective study of 13 cases]. / Le devenir du ciment phosphocalcique dans les cures d'enchondromes des phalanges et métacarpiens. Une étude rétrospective de 13 cas.

Chondromas are the most frequent benign tumors of the skeleton. The surgical treatment of these tumors consists of curettage of the tumor, which may be associated with a filling of the defect. One of the filling techniques uses bone substitutes. The primary objective was to evaluate the resorption of phosphocalcic injectable cements and their evolution in bone sites. The secondary objectives were to evaluate the function of the finger and to look for a possible recurrence of the chondroma. We performed a bi-centric study and reviewed 13 patients with 14 phalanx or metacarpal chondromas operated on by phosphocalcic cement filling technique with a minimum follow-up of 2years. An X-ray at the longest follow-up was performed as well as a QDASH, a "finger score" and a measurement of the amplitudes. Cement disappearance was observed in 100% of 5 patients. An average of 30% of cement remained at the last follow-up (0-80%). The disappearance of cement was significantly inversely proportional to the time since the last radiograph (P<0.01). On average, total disappearance of cement was found at about 6years postoperatively. The mean QDASH score was 6.1 (0; 40.91). The mean finger score was 3 (0-24). The disappearance of the cement seems to occur in the medium term after its installation but does not predict the functional recovery and satisfaction of patients operated on for the cure of a chondroma of the hand.

[Osteosynthesis by intramedullary headless screw in digital fractures: A retrospective scannographic and anatomical study]. / Ostéosynthèse par vis centromédullaire sans tête dans les fractures digitales : une étude rétrospective scanographique et anatomique.

INTRODUCTION: Long finger skeletal fractures are common injuries. In displaced forms, surgical treatment is required. With the advent of headless cannulated screws, the technique has been simplified and allows reduction in both planes. The objective of our study was to evaluate the functional recovery of patients operated on by this technique. MATERIAL AND METHOD: We conducted a retrospective single-center study between 2019 and 2022. Eleven patients were followed and 12 fractures analyzed. A radio-clinical follow-up was carried out at 1 month then at the last follow-up with an evaluation of the articular amplitudes and a quality of life score (QuickDash, QD). The time to return to professional and sporting activities, pain (EVA) was collected. An anatomical/scannographic evaluation was performed to assess tendon and cartilage damage. RESULTS: At the last follow-up, the average global flexion was 266° and the extension was total. An average QD score of 15.9 and a Jamar force of 106% compared to the healthy side were observed. The return to physical and professional activities was earlier and the pain quickly tolerable. No secondary displacement was objectified and all were consolidated at the last follow-up, without malunion. No patient had been operated on secondarily. CONCLUSION: This technique seems to be a safe and non-traumatic. It allows a faster return to sports and professional activities with fewer complications and no need to remove the material.

Early rehabilitation after reverse total shoulder prosthesis on fracture of proximal humerus in elderly patients provides better functional outcome.

PURPOSE: Reverse total shoulder arthroplasty (RSA) has revolutionized the management of proximal humerus fractures (PHF) in the elderly patients. There is few or no consensus regarding to management of postoperative rehabilitation in elderly patients. An early rehabilitation from D1 allowed better functional results compared to rehabilitation started to D30 independently from tuberosities consolidation. METHODS: 94 patients operated on for PHF were evaluated retrospectively, with a minimum radio-clinical follow-up of 2 years. Clinical evaluation included mobilities and four functional scores: ASES, quick DASH, gross constant, weighted constant. Radiological evaluation was performed on a frontal shoulder X-ray with evaluation of tuberosities' consolidation. RESULTS: The mean follow-up was 45 ± 19 months (24-88 months). Early rehabilitation was significantly associated with a better Constant Score (71.1 ± 17.2 vs. 56.4 ± 15.8; p < 0.001), better adjusted Constant score (92.4 ± 14.2 vs. 80.3 ± 19.5; p < 0.001), better quick DASH (22.8 ± 19.8 vs. 36.7 ± 21.3; p < 0.01), better ASES (78.6 ± 20.2 vs. 63 ± 22; p < 0.001). CONCLUSION: In traumatology, functional result of RSA seems not related in tuberosities' union but in rehabilitation in order to limit postoperative stiffness of operated shoulder. An early rehabilitation is related with better clinical and functional results, independently of tuberosities' union. LEVEL OF EVIDENCE: 3, control-case study.

[The incidence of hand trauma the COVID-19 epidemic setting]. / L'incidence des traumatismes de la main dans le contexte épidémique COVID-19.

OBJECTIVES: In France, a lockdown was enforced from March 17 to May 11, 2020. It was renewed with different modalities from April 3 to May 3, 2021. Our objective was to compare the epidemiology of hand and wrist trauma injuries during these periods to a control period, with the hypothesis of a decreased incidence of hand and wrist trauma. METHODS: Patients consulting at a trauma emergency center of a university hospital labeled SOS-Mains were included during lockdowns, and were compared with a control group who consulted during an equivalent period in 2019. We retrospectively collected demographic and clinical data in relation to hand and wrist injuries. RESULTS: During lockdowns, there was an increase in these injuries relative to the total number of patients (from 16% to 22% and 18%). We found a decrease during the first lockdown in the number of fractures, amputations, burns, infections, injuries secondary to a work accident and isolated wounds but a significantly higher proportion of tendon and vasculonervous injuries in the first lockdown (12% vs. 4%). CONCLUSIONS: In first lockdown, the incidence of hand and wrist injuries decreased, but there was an increase in tendon and microsurgical injuries. This may be explained by the change in leisure activities. This underlines the importance of preventive measures concerning the risks related to some activities (use of sharp/motorized tools) in this context of health crisis.

[Use of coupler for venous anastomoses in cervico-facial reconstruction. Retrospective study on 51 free flaps]. / Utilisation du coupleur pour les anastomoses veineuses en reconstruction cervico-faciale. Étude rétrospective sur 51 lambeaux libres.

OBJECTIVE: The aim of our study was to evaluate the interest of the mechanical anastomosic coupling device for venous anastomoses in a series of cervico-facial reconstructions after carcinologic excision. PATIENTS AND METHODS: Between January 2010 and December 2017, 46 patients underwent free flap cervico-facial reconstruction. We performed 54 venous anastomoses for 51 free flaps. Mechanical venous anastomoses were performed with a coupler (Coupler®). Thrombotic complications and choice of recipient vessels were assessed for the entire series. RESULTS: Venous anastomoses were performed using a coupler in 33.3% of the flaps (n=18). Mean operative time was lower for reconstructions with mechanical coupler anastomoses, and significantly for fibula flaps. Of eight thromboses, six were venous, two of which after the coupler anastomosis. The thrombosed veins were the branches of the internal jugular vein and the anterior jugular veins. The diameter of the couplers used was respectively 2.5mm and 2mm. CONCLUSION: The use of the microvascular coupling system for venous anastomoeis would help reduce the occurrence of venous thrombosis, but larger and prospective studies should be conducted. This coupling system, relatively easy to use, would overcome the lack of congruence of anastomosing veins and reduce the risk of intimal injury. Regarding the recipient vessels, the anterior jugular vein should not be used as first line because the risk of vascular complications seems more important.

Treatment goals for distal radius fractures in 2018: recommendations and practical advice.

The goals of distal radius fracture treatment in patients above 65 years of age would not change over time if the fracture were the only factor to consider. However, people change, and fixation methods also change. Since this fracture heals in nearly every case and volar plates have eliminated the worry of malunion, we are left with two main goals. In active patients with weakened bones, the aim is to help them regain their quality of life as quickly as possible while avoiding iatrogenic conditions. This compromise is possible because of new tools-but at what price?

Cementless and locked prosthesis for the treatment of 3-part and 4-part proximal humerus fractures: prospective clinical evaluation of hemi- and reverse arthroplasty.

INTRODUCTION: Cemented stem remains the gold standard for prosthesis in trauma. The purpose of this study was to evaluate the functional and radiological outcomes of a cementless, trauma-specific locked stem (hemi and reverse) for 3- and 4-part proximal humeral fractures. MATERIALS AND METHODS: One hundred and thirty-four 3- and 4-part fractures have been treated by locked stem, 69 with hemiarthroplasty [mean age 68 years (50-90)] and 65 with reversed [mean age 78 years (66-91)]. The length of the stem was 15 cm with a proximal coating of HA automatic locking system (two screws) and four different diameters. Preliminary cadaver study allowed us to validate the system (22 shoulders, no injuries of nerves, locking system efficient). RESULTS: In the group of hemi, Constant score with ponderation reached 72 (11-120) and QDash 31.2 (4.5-77.27) with a mean FU of 25 months (6-96). In the group of reversed, Constant score with ponderation reached 77.6 (28.8-119) and QDash 36.2 (2-84) with a mean FU of 15 months (6-41). Specific complications due to locking system reached 3% but without reoperation. Other complications were capsulitis and infection. DISCUSSION: In this population of elderly patient, new fall with periprosthetic fracture or infection led the surgeon to remove the stem. At shoulder level, the removal of a cemented stem remains a highly demanding procedure with sometimes bad functional results and elevated level of complications. This series is the first one of locked stem without significant complications. Locked stem remains a new but logical tool in trauma.

Anatomical and computed tomography study of the eighth costochondral junction: topography for costochondral graft harvesting.

INTRODUCTION: Costochondral grafts have long been used in maxillofacial reconstruction, but have been little used in trauma and orthopedic cases. This surgical technique requires that a graft be harvested from the thorax in the area of the eighth rib. Pleuropulmonary complications are very rare. Although the harvesting technique is simple, it needs to be demystified. GOAL OF STUDY: This study was performed to define anatomical relationships in the eighth costochondral junction and identify topographical and anatomical landmarks that will make it easier to harvest this structure. METHOD: This was a two-part study. First, an anatomical study was carried out on human cadaver thoraxes to define topographical landmarks and study the anatomical surroundings of the eighth costochondral junction. Second, an imaging study was performed using a database of existing patient computed tomography (CT) scans of the chest and abdomen to confirm the topographical landmarks defined in the first part of the study. The spine was used as a reference for both studies. The location of the eighth costochondral junction was defined relative to the spinal processes along with its location on the lower rib cage hemiperimeter in the transverse plane starting at the corresponding spinous process. RESULTS: The eighth costochondral junction was in line with the spinal process of the twelfth thoracic vertebra in the vast majority of cases and located at two-thirds of the lower rib cage hemiperimeter from the posterior median sulcus, regardless of the patient's chest shape, age and gender. This junction was always located under a single muscle (external oblique) and protected by a thick perichondrium layer, which separates it from the intercostal pedicles, endothoracic fascia and parietal pleura. DISCUSSION: This two-part study has identified reliable landmarks for harvesting of an osteochondral graft at the eighth costochondral junction and, by describing its anatomical surroundings, helps take the mystery out of its harvesting. These landmarks were identified in supine cadavers and in free-breathing patients lying in supine for the CT portion. This position must be used when identifying these landmarks in a patient undergoing costochondral autograft harvesting for cartilage reconstruction.

How to determine the bone mineral density of the distal humerus with radiographic tools?

INTRODUCTION: The aim of this study was to investigate three methods of prediction of the bone quality of the distal humerus: dual-energy X-ray absorptiometry (DEXA), Ct-Scan and plain radiographs. MATERIALS AND METHODS: The bone mineral density (BMD) of 21 cadaveric distal humerus was determined using DEXA at two levels. Then a CT-scan and anteroposterior radiographs were taken. The cancellous density was estimated with the CT-scan. The cortico-medullar index (CMI) was calculated as cortical thickness divided by total bone thickness on AP views. RESULTS: A significant positive correlation was found between the BMD of the epiphysis and the CMI of r = 0.61. The mean BMD of the distal humerus was 0.559 g/cm(2). Male specimens showed a significantly higher BMD than females. The mean CMI of diaphysis was 1.431 and the mean BMD of the metaphysis region was 0.444 g/cm(2). DISCUSSION: More than a direct evaluation of the bone density with a CT-scan, the CMI of the distal humerus diaphysis is a predictor of the bone quality of the distal humerus. This should be of great help for the surgeon's decision making in case of fracture of the distal humerus, as open Reduction and Internal Fixation (ORIF) of fractures of the distal humerus can lead to failure due to poor bone quality. LEVEL OF EVIDENCE: Basic Science Study, Anatomic Cadaver Study.

Dimensions of the trapezium bone: a cadaver and CT study.

PURPOSE: The primary purpose of this study was to define the size of the trapezium bone through measurements on cadaver specimens and CT scans of living subjects. The secondary purpose of this study was to determine if any correlation existed between the size of the trapezium and local anatomical parameters. METHODS: The radio-ulnar length (L), dorsopalmar width (ℓ) and height (h) of the distal surface of the trapezium were measured by two independent observers on 20 cadaver specimens. The same measurements were carried out by two other observers on anonymized CT scans from 18 patients. The inter- and intra-observer agreement was determined using the intraclass correlation coefficient. RESULTS: In the cadavers, the mean length, width and height of the trapezium were 22.8, 15.5 and 15.2 mm, respectively. On the CT scans, these same dimensions were 19.2, 11.4 and 11.6 mm. Inter-observer agreement was statistically significant in both parts of the study. DISCUSSION: The dimensions of the trapezium bone were about 3.33 mm larger in cadavers than on CT scans. These differences can be explained partially by a systematic under-sizing error on the CT scans and the fact that the cartilage layer cannot be directly visualized. CONCLUSION: This study was able to define the dimensions of the trapezium bone. It may be possible to predict the trapezium height from the length of the forearm or the width of the radial epiphysis. Our data can be used to adjust the size of trapezium implants to the dimensions of the patient's bone.

Hand and wrist Osteo-articular bone defect: induced membrane technique indications.

Bone defect in the hand and wrist is the result of 3 main causes: traumatic, infectious or tumoral. Whatever the cause and possibility of emergency management, the site (hand or wrist) and anatomical location (articular or diaphyseal) guide the choice of surgical technique and timing. Functional sequelae do not vary, and the ultimate objective is not so much to fill a defect but to give a useful and accepted finger, hand or wrist.

ISIS trapeziometacarpal arthroplasty: What are the outcomes in male patients?

Trapeziometacarpal arthroplasty is a well-known treatment of thumb basal joint arthritis. However, only a few studies have been done on its use specifically in men, with one of the most recent showing a high implant failure rate. Our study was a retrospective analysis of the ISIS prosthesis exclusively in men. Our hypothesis was that it is a viable therapeutic solution. Between 2010 and 2020, 23 ISIS prostheses were implanted in 19 patients. A radiological and functional analysis was done, combined with a self-evaluation by multiple validated outcome scores (visual analog scale for pain, QuickDASH, PRWE, SF36, and Kapandji scores). The median follow-up was 76 months (13-134) with a median age of 69 years. The mean pain level was 1/10, the QuickDASH was 22.7, the PRWE was 14.2, the SF-36 was 61.1 and the Kapandji score was 8.9. One dislocation occurred in one patient; two patients had to be reoperated for periprosthetic ossifications. Radiolucency was found around the cup in one patient and around the metacarpal shaft in one patient. There was no implant failure and only one case of asymptomatic loosening, with a survival rate of 94% at 111 months. In the medium-term, clinical, and functional outcomes were satisfactory with pain relief similar to that of published studies, with a low rate of complications. ISIS arthroplasty appears to be a suitable treatment for thumb basal joint arthritis in men, although a non-negligible rate of periprosthetic ossifications required revision surgery in half of the cases.

Techniques to prevent symptomatic neuroma in digital amputations.

The occurrence of a symptomatic neuroma on a digital amputation stump, whether traumatic or not, is a frequent complication that affects the patient's quality of life. The objective of this study was to analyze the complications inherent to the various techniques used to manage the nerves when performing digital amputation. We compared different surgical nerve management techniques to determine if one technique is more effective than another in preventing neuroma occurrence. We reviewed 105 patients over a 5-year period. A DN4 score greater than 4 and the modified Tinel test (percussion) showing a trigger zone allowed us to clinically diagnose symptomatic neuroma-related pain. We found 23 symptomatic neuromas out of 131 digital amputations. Twelve neuromas were found when the nerves had been neglected (12/33), eight were found in nerves treated by stripping (8/60), three when nerves were treated by stripping and thermal ablation (3/18). No neuroma was found in the five cases of centrocentral union of the two proper palmar digital nerves, in the 5 nerves buried in the bone or in the 9 nerves subjected to thermal ablation only. Management of the nerve is essential for the prevention of neuromas in digital amputations. New techniques such as bone burial and centrocentral union of the two stumps appear to be particularly effective.

Arthroplasty for destroyed proximal interphalangeal joint in hand trauma surgery: Silicone hinged NeuFlex® or gliding Tactys®?

The treatment of proximal interphalangeal joints (PIP) after a traumatic injury has produced disappointing outcomes. The objective of this study was to evaluate the functional results of emergency hinged or gliding arthroplasty for destroyed PIP joints. A two-center retrospective study was carried out in 24 patients with open and closed trauma of the PIP joint of the fingers from 2007 to 2019. Fifteen hinged silicone implants (NeuFlex®) and nine gliding implants (Tactys®) were used. Pain on a visual analog scale (VAS), stability and total active motion (TAM), grip and pinch strength (Jamar®), QuickDASH and PRWE and satisfaction were assessed, and X-rays were performed. With a mean follow-up of 48 months, 24 patients aged 58 years on average were reviewed. Pain on VAS was 0.2/10, the TAM was 72% of the contralateral side, the QuickDASH was 15.6/100 and the PRWE was 24.5/100. PIP flexion was ≥50% of the contralateral side in 75% of patients. PIP and DIP extensor lag of 9° was significantly larger with the Tactys® than with the NeuFlex®, with no significant difference in the TAM. Three clinodactylies in fingers with the NeuFlex® and three reducible swanneck deformities in fingers with the Tactys® were noted. Three-quarters of patients were very satisfied or satisfied with the outcome. Emergency PIP arthroplasty with Tactys® seems to provide functional results that are as good as with NeuFlex®. Clinodactyly was found with NeuFlex® use. A significant PIP and IPD extensor lag of 9° and swan-neck deformities were found with Tactys® without significant functional impairment.

Traumatic lesions at the thumb base: Treatment options.

Traumatic lesions around the base of the thumb have special features due to the location and structure of the joint and its inherent potential instability. This causes different fracture patterns, which are mostly isolated around the metacarpal base but can also involve just the trapezium or both. Exceptionally, there may be isolated dislocation. Fracture patterns are variable and influence the type of surgery. The most common fracture is Bennett's fracture accounting for 4% of all hand fractures and sometimes associated with trapezium fracture, usually in male subjects. Different fracture mechanisms have been proposed. Apart from intra-articular fractures of the metacarpal base and the trapezium, proximal metaphyseal fractures can exceptionally be treated conservatively by immobilization. All other fractures require open or closed reduction combined with different types of temporary pinning or open reduction and internal fixation with screws or locking plate in case of comminution. Immobilization depends on the type of surgical treatment and can be removable or non-removable. Close follow-up is mandatory to avoid the inconveniences of secondary swelling with non-removable plaster and resin casts. Extra-articular malunion may be tolerated, but articular malunion must be corrected surgically by intra-articular osteotomy to restore the joint. In case of posttraumatic joint degeneration, treatment will focus on a case-by-case basis on the patient's complaints. Arthrodesis or prosthetic surgery can be proposed in case of severe problems caused by osteoarthritis.

Nerve regeneration conduit from inverted human umbilical cord vessel in the treatment of proper palmar digital nerve sections.

Treatment of digital nerve injuries, particularly in case of a gap, is challenging. Recovery of finger sensitivity is often incomplete and can impair personal and occupational activity. The need for better nerve regeneration has given rise to alternative treatments such as nerve conduits. This study aimed to evaluate the safety and efficacy of a conduit of freeze-dried inverted human umbilical cord vessel for regeneration in digital nerve section. Twenty-three patients with a mean nerve gap of 6.11 mm (range 2-30 mm and static 2-point discrimination (s2PD) > 15 mm underwent surgical repair of digital nerve section using a nerve regeneration conduit. The primary endpoint was recovery of sensitivity after conduit implantation. Secondary endpoints comprised progression of pain, functional symptoms, pressure threshold, hand-specific symptoms and disabilities, and restored innervation. Mean follow-up was 10.1 ± 4.1 months (range 1-14 months). Sensitivity recovered progressively in the months following implantation. There was a mean decrease of 8.54 mm in s2PD between baseline and last follow-up (p < 0.001). Complete innervation recovered in 83.3% of cases at last follow-up. Pressure threshold and hand-related quality of life improved significantly and symptoms due to nerve sectioning (pain, cold intolerance, hypoesthesia, hyperesthesia) resolved almost completely. There were no safety issues related to the nerve conduit. These results indicate that freeze-dried inverted human umbilical vessels can be a safe and effective option as conduit for digital nerve regeneration.

Anatomical and radiological study applied to distal radius surgery.

PURPOSE: The purpose of this study was to determine, during anterior plating of the distal radius, the length of a screw above which there is a risk for the extensor tendons and the optimal shape of an anterior plate. It was also to determine the projection of the axis of the distal third of the radius on the distal articular surface in case of wrist arthroplasty in order to simplify the procedure. METHODS: We studied 74 dry radii from adult cadavers. Each one underwent a CT scan. We measured the thickness of each radius at the dorsal tubercle level, at the second compartment level and at the third compartment level. We calculated the metaphyseal-epiphyseal angles of the lateral column and of the intermediate column (Rikli and Regazzoni in J Bone Joint Surg (Br) 78(4):588-592, 1996). We also calculated the projection of the longitudinal axis of the most distal 7 cm of the radius on the distal carpal surface of the radius. RESULTS: Mean thickness at the dorsal tubercle level was 22.1 mm (18-26.1). The mean slope of the lateral column was 155° (143-167) while that of the intermediate column was 145° (134-153). We have found a statistically significant difference (p < 0.0001) between these two slopes. The axis of the distal radius was projected on the posterior-lateral quadrant of the distal articular surface. CONCLUSIONS: The emergence of new implants needs a precise evaluation of a fractured, an arthritic or a reconstructed distal radius. The double slope of the distal radius complicates the manufacturing of an "anatomical" plate. The optimal shape is between these two slopes. Moreover, ancillaries for wrist replacement are still approximations, which means that it is important to know the projection of the radial axis on the articular surface of the distal radius.

[Baropodometric analysis of the functional donor-site morbidity after gastrocnemius or soleus muscle-flap procedure]. / Analyse baropodométrique des séquelles fonctionnelles liées au prélèvement des lambeaux gastrocnémiens et soléaire.

The triceps surae muscle is a major donor-site for muscle-flap to cover soft-tissue defects of the leg. There are very limited datas on the functional donor-site morbidity in the literature. From a retrospective study on 14 patients, we realized a baropodometric analysis comparing the operated lower limb with the healthy non operated side and a functional evaluation by a questionary. The modified functional score of Kitatoka was good (87/100). Ninety percent of the patients were able to resume a professional activity and 2/3 to resume the sport. The baropodometric analysis did not show statistically significant difference of propulsion and absorption between the healthy side and the operated side, but a modification of the programming of the step. The absence of important functional donor-site morbidity is probably bound to a compensation of the remaining triceps surae muscles and/or to mechanisms of adaptation. Our study confirms the little functional donor-site morbidity of the partial triceps surae muscle-flap procedure. These flaps remain a good solution for the coverage of the soft-tissue defects of the leg.
